CANDYADRAWING MACHINE.

.ApplicationL filedA July 7',A

To all whom t may/concern:

Beit known that I, ERNnsr L. HAMILTON, a citizen of the Unitedv States; residing at Minneapolis, in the county of Hennepin and State of'Minnesota, have invented certain new and useful` improvements in f Candy- Drawing Machines; andI ldo hereby Kdeclare the followingfttov be 'afulh clear, and exact description of theA invention, such as will enable othersskilled inthe art to which-it appertains to make and'use thesame.`

This invention-relates to a `machine for operating :on candy-'and :particularly tosuchf a machine in whichv theA candy; isfdra/wn. Certain kinds of "candy are vnowA made :substantially in the-formfo ftaiiy'and after this taffy has beenftreatedA to a certain extent by pulling, and otherwise, theisame isdrawn out inthe form offa-mibbonvand: cntiinto various shapes.

It is an objectofthis.- invention toy provide a machine. for N feeding.: and# drawing longitudinally a v batch: Yor 1 rollA of such tay or taly-like candy.`

It is a further object voff-'the invention to provide such: a. machine V- comprisingv a series of rings-havingthei-r openingsffrmi'n'g a continuous channel through Whichthe candy is progressed.

It is also `an objectothe invention to provide suitable means forldelivering the candyvto such.' channel "and-tor forming the 'candy after the same has passed therel through.

It fis morespecifically an: object of thefinvention to provide a niachinehaving a chan-I nel: formedby the tapered openingsof -adjacent rings, said openings` being oppositely threaded inI adjacent rings and adjacent rings 4being/rotated in opposite directions.:

These andfo'ther objectsy and advantages of the invention willf'be more i-'Illy set forth.- in thefollowing:descriptionv made in connectioni with: the;*accomp1i-lying drawings in which like reference characters refer to the-V same parts throughout thefditterent views,f andI in which,y v

The bearing brackets 11 extend some distance across the frame 3 and are arranged to carry a second shaft' 15 extendingparf. allel tothe shaft 10.'y The'shaft 15 isadapted to be ldriven from the shaitQ 4by a beveled gear and pinion not shown, substantially `as carry a series of spur-gears -16 o't-:respec tively different diameters`,z which gearsv` are arrangedy to mesh with the teethforincd oni thelperipherie's of' a series of co-axial rings 17 supported on-ball bearingsE 18 running infball rraces formed in the frame'members 11 andfin-the sides 4ot saidl rings It will( be noted that the ringsv 17 are provided on oneside with arecess adjacent the openings thereinJ and on the other side with a. projection, which recesses and projectionsy are adapted to iit'together so that the rings are supported* and guided in` alinementf The,

m incasso be obvious that adjacent ones of the rings 17 are driven in opposite directions. lt will be noted that the openings in the rings 17 are tapered and arranged to form a continuous conical passage of circular cross section. Said rings are interiorly threaded and the threads in adjacent rings are oppositely inclined, that is, that one ring is provided with a right hand thread while the adjacent ring is provided with a left hand thread.

The ksaid threads are also preferably of progressively steeper pitch from the ring having the larger opening to the ring having the smaller opening. lt will be noted that the end of trough 6 extends into one of the frame members 11 adjacent the ring having the larger opening, and a flaring discharge tube 19 vtits into the other end frame member 11 having its end adjacent the ring of smallest diameter.

The tube 19 is arranged adjacent and in alinement with the opening between a pair of flanged rolls 20 revolving on vertical axes and the opening between rolls 20 is in alinement with that between a pair of flanged rolls 21 adjacent thereto and revolving about horizontal axes. The rolls 2O and 21 revolve in the directions indicated by the arrows in Fig. 1 and said rolls will be driven b some suitable form of earing` and the rolls of said pairs will` preferably be arranged to be adjustable toward and from each other. f

As shown in Fig. 1, the lower surface of the channel formed by the rings 17 is arranged substantially horizontal or with a slight inclination downward. The trough 6 will also be adjusted by the nut 5 tobe substantially horizontal or to have a slight downward inclination. The batch or roll of candy is placed in the trough 7 and by the oscillating movement of this trough and the semicylindrical shape of the bottoni thereof, will be given more or less of a rounded shape on its lower side. The candv will be more or less drawn out into a roll and the end thereof will rbe sufliciently' small to be inserted through the channel 'formed by rings 17 and engaged by the rolls 20. rIhe machine now being driven, the candy is engaged by the threaded or ribbed interior surface of the ring 17 and owing to the inclination of these ribs is given a longitudinal movement or pull. If the rings 17 were all driven in the same direction the candy would have a tendency to roll up along the surface of the ring and for this reason the adjacent rings are driven in opposite directions, which tends to keep' the candy centered in the bottom of the channel. As the candy progresses through the channel formed'bj.7 said rings, it will be drawn out more and more, due to the increased pitch of the threads or ribs on the interior surfacev of they rings and owing heb to the increased speed o the interior surface of the ring 'lle candy will thus be drawn out into a thin portion as it passes through the ring 1.7 and will be delivered out through the tube4 1S). rl`his thiny roll of candy will then be engaged by the rolls 2O and formed into a more or less flattened shape and will then pass through the rolls 21. By the action of these two pairs of rolls a flat bar of candy of substantially uniform width and thickness will be formed which can then be cut up into the desired shapes. 1t will be obvious that the distance between the pairs of rolls E20 and 21 may be varied as desired and that the. inclination of the frame Semay be suitably varied to give the desired results.

From the above description it is seen that applicant has provided a simple and efficient candy feeding and drawing inachine and one which will automatically and etticiently draw the candy into a bar of small cross section. The machine once started will need practically no attention and the candy will be progressed therethrough in a clean and sanitary condition.

It will, of course, be understood that various changes 'may be made in the form, details and arrangement of the parts withoutdeparting from the scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth in the appended claims.

l0. A candy handling machine comprising a tapered channel circular in cross section having longitudinal sections thereof provided with ribbed surfaces, said ribs being oppositely inclined in adjacent rings, and means for rotating adjacent rings in opposite directions the axis of said rings being inclined to the vertical.

11. A candy drawing machine having in combination, a series of adjacent annular membersforming a runway therethrough, the adjacent ones of said members moving in opposite directions, and means on said members adapted to act on the candy and progress the same in one direction along said runway. v
